IMPRGVEMENT IN APPARATUS FOR WARMING STEAM-FIRE-ENG|NE HOUSES.

Specification forming part of Letters Patent N0. 150,938, dated May 19, 1874; application filed April 16, 1874.

To all whom it may concern:

Beit known that I, HENRY V. COLEMAN, of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Apparatus for Warming Steam-FireEngine Houses, of which the following is a specifica tion:

The natureof this invention relates to the combination, with the circulating waterheat ing apparatus used in enginehouses for keeping the water in the fire-engine boiler` hot ready to generate steam, of hot-water coils and radiators, for warming the engine-room during cold weather by the waste heat; it also relates toa novel method of warming the upper rooms by the columns of air passing up through the boiler-tubes, the entire interior surface of the boiler serving as a radiator to heat the ascending air-currents, so that the engine-house may be kept comfortably warmed, without the expense of operatin g stoves or a furnace for that purpose.

Figure 1 is a perspective view, showing portions of the main and upper floors of an engine-house; it also shows the heater in the basement, a portion of the lire-engine on the main floor, and the arrangement of the hot- `tical section of the hot-air iiues and chimneyhood.

In the drawing, A. represents the boiler of a steam fire-en gine, standing in its place in the engine-house. B is a hot-water coil or radiator. C is the circulating water-heating boiler in the basement, such as is used for keeping the water in the engine-boiler hot. L is the service-pipe and cock for supplying it with water when needed. D is a register in the upper oor directly over the smoke stack of the engine when the latter is in proper place. From the register is suspended a flue, D1, which may have one or more lateral ilues leading to other rooms overhead. In the 4 lower end of the flue is sleeved a hood, D2,

suspended from a cord, a, passing over guidepulleys b b, and down toa lever, G, below the main floor. F is the flow-pipe from the heater, and B is the returnpipe thereto. The former terminates in a three-way cock, o, whose plug is actuated by the lever G. From the cock c issues a rising flow-pipe, F1, coupled by a slipjoint, f, to the flow-pipe F2 ofthe en gine-boi1er. R2 is the return-pipe from the said boiler, connected by a slip-joint, f', with a drop returnpipe, B1, which enters a threeway cock, d, to whose end is connected the flow-pipe B1 of the coil B. To the other outlet of the cock d is connected the bent upper end ot' the returnpipe R ofthe heater. The return-pipe B2 of the coil is connected by a T with a pipe, F2, one end of which communicates with the cock c, and the other with the bent end of the return-pipe It; but between the latter and the T is a stop-cock, e, actuated by the lever G. The cock c is actuated by a lever, H, which, with the lever G, is connected or pivoted to the lower end of a rod, I, which'projects up through the floor. The engine being in the position shown, and the rod I pushed down, hot water issuingfrom the heater C through the pipe F will pass through the cock c and pipes Fl F2 into the engineboiler. The colder water will issue from said boiler through the return-pipes B2 R1, passing through the cock d and pipe B1 into the coil B, returning through the pipes B2 F3, stop-cock c, and return-pipe It, to the bottom of the heater-boiler, the course of the currents being indicated by arrows in Fig. l. The colder air near the loor passes up through the lire-box and tubes of the engine, where it is warmed by contact with the heated metal. Issuing from the smoke-stack it passes through the hood D2, flue D1, and register D, into the mens sleepin g-room above 5 or a portion of the heated air may be taken by a lateral flue to another room, as indicated in Fig. 2. When the engine is to leave the house the rod I is pulled up to shut oil' the flow to and from the engine through the cocks c d, and to close the cock c at the same time the hood D2 is lifted clear of the stack. The water now issuing from the heater will rise through the pipe F and cock c, and pass through the pipe F3 into the pipe B2, thence through the coil B, back through B1, d, and R, to the heater, reversing theflow through the coil. M is a gage on the coil to indicate the water-pressure.

WhatI claim as my invention, and desire to secure by Letters Patent, is=

1. The combination, with a steam nre-engine and a fire-engine water-heater, of one or more combination with a. steam ire-engine and hot-water coils, B, substantially as described, Water-heater pipes7 for the purpose of heatiu g and for the purpose of heat-ing the engineone or more rooms above the engineroom, room, as set forth. 1 substantially as shown and set forth.

2. The combination of the ii es B B B2 with the cooks c d e, and pipes FlFpF2 F3 R R1 R2, HENRY V' COLEMAN' levers G E, and rod I, as and for the purpose Witnesses: set forth. WM. H. Lo'iz7 3. The register D7 Hue D1, and hood D27 in HERMAN BISOHOFF.
